Problema Solution
Find the number of 2 3/4 gallon cans which can be filled from a tank containing 90 3/4 gallons of oil.
Answer provided by our tutors
2 3/4 = 2 + 3/4 = (2*4)/4 + 3/4 = (2*4 + 3)/4 = 11/4
the can is 11/4 gallons
90 3/4 = 90 + 3/4 = (90*4)/4 + 3/4 = (90*4 + 3)/4 = 363/4
the tank is 363/4 gallons
let 'x' be the number of cans that can be filled from the tank then we can write
(11/4)*x = 363/4
by solving the inequality we find
x = 33 cans
